Study Shows Beans and Potatoes are Lowest-Cost Sources of Potassium and Fiber

July 9, 2013 - PRLog -- In a study published by PLOS ONE, researchers analyzed cost metrics vs. nutrients in vegetables in relation to beans and potatoes. Those cost metrics showed that, not only are beans and potatoes cheaper per calorie, but also account for the lowest-cost source of potassium and fiber.

The study, printed on May 15, 2013, considered fresh, frozen, and canned vegetables. Researchers used the study to estimate the cost of meeting new United States Department of Agriculture National School Lunch Program requirements.

Within the cost metrics provided by the study, it's shown that beans and legumes account for the most potassium and fiber at the lowest cost. Cost and nutrient density were two main factors in the study, as was consumer acceptance. According to the authors, of the vegetables and starches studied, "only beans, white potatoes and carrots managed to combine nutrient density, affordability and consumer acceptance."

In conclusion, the authors ascertain that, when considering school lunches, foods served should be nutrient dense, inexpensive, and accepted by schoolchildren as something they'd like to eat. According to the study, beans fit the description to a tee!
